Sydney stocks followed Wall Street's lead, but gains were limited by warnings that the market has reached sensible valuations, and sentiment was not helped by news of a 47% slide in the profits of resource giant WMC. Although the mining company's stock slipped sharply, other miners held up well on longer term earnings considerations, and with News Corporation stock up a further 2.2%, the All Ordinaries index added 12.2 points to close at 3380.1.
